Panelized construction offers benefits to the construction industry including energy savings and reductions in carbon emissions and waste. This research addresses the sustainability of panelized residential construction during the framing phase, which consists of panel fabrication in the plant, transportation to the site, and on-site assembly. This study is conducted in collaboration with Landmark Building Solutions (LBS), a panel manufacturer in Edmonton, Canada. Two tasks with respect to assessing the sustainability of panelized construction are carried out in this research: (1) The positive impact of panelized construction on the construction schedule is evaluated by utilizing archived schedule data. In this task, the cycle time of framing for panelized construction is investigated; the results are compared with those of conventional stick-built construction, and the impact of framing cycle time on on-site winter heating is addressed. (2) The benefits of panelized construction are measured in terms of construction waste reduction by quantifying the recyclable and non-recyclable waste. The results are compared with those of the stick-built method, and the impact on embodied emissions in material waste is addressed. The primary data source is archives of the industry partner, including accounting records and construction records. A literature review and comparison are carried out to provide the necessary context for achieving the research objective. The preliminary results support the sustainability of panelized construction compared with the conventional stick-built method.
